DOOR-LOCK.

$PECIFIGATION forming part of Letters Patent No. 289,031, dated November27, 1883.

Application tiled September 19,1883. tModel.)

To all whom it may concern.-

Be it known that we, J onn SOHILLIXG and ABRAM Annnnr Mnssiin, citizensof the United States, and residents of Pomeroy, in the county of -Meigsand State of Ohio, have invented certain new an d useful Improvements inLocks; and we do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertainsto make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which Figure l is a side view of the entire lockmechanism with one side of the lock-casing removed. Fig. 2 is ahorizontal section of the same on line a as, Fig. l; and Fig. 3is avertical sectional detail View on line 3! 1 Fig. l.

Similarletters-of reference indicate corre sponding parts in all thefigures.

Our invention has relation to that class of locks in which the l0ck-boltforms a frame, inside of which a slide operated by the key slides,serving to lock the lock-bolt by hearing against the inside of theforward end of the frame; and it consists in the improved constructionand combination of parts of the same, as hereinafter more fullydescribed and claimed.

In locks of this class the slide which holds the lock-bolt locked hasheretofore been sliding vertically, bearing only with one corner againsta shoulder in the outer end of the frame, by which construction it hasbeen possible to force the lock-bolt back, the point of resistance beingcomparatively small; and to avoid this we construct a lock in which theslide operated by the key bears with its entire outer end against theouter end of the frame when locked, the slide sliding horizontally, thusholding the lock-bolt perfectly secure in place.

In the accompanying drawings, the letter-A indicates the casing, whichis of the usual construction, and may be made to serve for a mortise orface lock, as desired.

B is the bolt, which is shown in the drawings as having a beveled facefor use in a face-lock, and the inner portion of which forms an openframe, C, having a half-round recess, D, in its inner end and arectangular recess, E, in its outer end to the rear of the beveled outerend of the bolt.

A sleeve, F, having a central perforation, G, for the reception of thelock-spindle, and having two diametrically-opposite arms or lugs, H,upon its sidesflturns in perforations I in the casing and in thehalf-round recess in the bolt, and the lugs bear, when the bolt isforced out, against one of two pairs of shoulders, J, upon the rear endof the bolt, one pair of shoulders being on each side of the bolt.

A spring, K, bears with one end against the inner side of theloclrcasing, fitting into a notch in the same, and bears with the otherend against the rear end of the bolt, fitting in a notch in the same,forcing the bolt out, while by turning the lock-spindle and sleeve oneof the arms upon the latter will press against one of the shoulders uponthe bolt, forcing it back.

In the rear side of the casing is pivoted a lever or catch, L, havingone end projecting outside the casing, while its other end will bearagainst the rear end of the bolt when tilted downward.

M is the slide, the outer or forward end, N, of which is rectangular,fitting into the rectangular recess in the bolt, while its lower edge iscut out at O, to correspond to the shape of the key, which is insertedthrough the keyhole 1?, and the lower edge is cut out to the rear of thenotch O for the key, to form two half round notches, Q, having a roundedbulge, R, between them, which notches iit over a pin, S, fastened in thelock-casing, the foremost notch fitting over the pin when the slide ispushed back, releasing the bolt, and the rearmost notch fitting over thepin when the slide is pushed forward, looking the bolt.

Afiat spring, T, fits with one end into a notch in the upper edge of theslide, and bears with its upper side against a pin, U, fastened in thecasing above the slide, and serves to force the latter down against thekey and force the notches to catch over the lower pin. In this manner itwill be seen that the lock may be used as a common latch by unlockingthe slide, while by locking the slide it will prevent the bolt frombeing drawn back. It will also be seen that the lock may be used as aright or left handed look, as desired, byturn- 'ing the bolt, bringingthe beveled face to either side, there being two pairs of shoulders uponthe rear end for the lugs upon the sleeve to act upon.

\Ve are aware thatlocks have been inade with the inner portion of thelock-bolt forming a frame, against the outer end of which a slideoperated by the key may bear when looked, as shown in Patent No. 217,693,

granted to E. A. Kimball July 22, 1879, and

we do not wish to claim such construction, broadly; but

lVhat we claim, and desire to secure by Let tersPatent of the UnitedStates, is

\ The combination of a lock-bolt having ineans for operating it andforming aframe at itsjinner portion, having a rectangular recess at itsouter end, with a key-operated horizon--
